| 摘 要： | 利用Gleeble 1500热模拟实验机进行单轴压缩实验,研究了工业纯铁和两种不同含碳量的低碳钢在700℃、不同应变速率条件下的热变形行为.实验结果表明,变形组织中的珠光体对铁素体动态再结晶行为具有重要影响,即增加钢中珠光体含量,可以促进铁素体动态再结晶过程的发生和发展,使得可以发生铁素体动态再结晶的应变速率范围变宽.

| Abstract: | Hot deformation behaviors of pure iron and two kinds of low carbon steels with different pearlite contents were investigated by hot uniaxial compression using a Gleeble 1500 hot simulation testing machine at a deformation temperature of 700℃ and strain rates of 10 to 0.001 s-1. The results indicate that pearlite has an important effect on the behavior of dynamic recrystallization of ferrite, that is, the increase of pearlite content promotes the dynamic recrystallization process of ferrite and broadens the range of strain rate in which this process can occur. |
